turbo 6 bangers post here
I don't know a lot about turbo sizing. (That's an understatement!)
You'd think somebody selling something like that (an aftermarket turbo,) in the interest of having satisfied customers (people who bought and installed this item on the correct-sized motor) would, at LEAST, say something like,
"this turbo will work well on mildly tuned motors in the displacement range from 200 to 280 cubic inches, if rpms are limited to approximately 5500. Of course, smaller engines can go higher and larger engines might start losing torque a little sooner."
That sort of information might prevent a newbie (like me) from choosing that turbo for, say, a 360 Magnum motor. Or, a Fiat 500.
That kind of mistake can happen very easily, because turbo sizing takes some education to do "right" and not a lot of people have it. I sure don't.
It's up to the vendor, and in HIS best interest to provide at least, ballpark figures on which engines might could benefit from this particular unit, because HE's the one who's going to have to deal with unhappy customers (returns, bad feedback, or whatever,) if it turns out not to work well on the intended engine because of
sizing issues.
Tom Wolfe (
Shaker223 on FABO) installed a junkyard Buick G/N turbo on an otherwise stock 225, that had either a 2bbl or a 4bbl added (I can't remember which,) in a 3,300-pound 1970 Dart and went 12.95 @ 102 mph, but he was running 18 pounds of boost to do that.
That amount of boost is not healthy for a stock short block. Ten pounds is probably about as much as the stock setup can endure and live a reasonably long life. We're talking pump gas, here...
At ten pounds of boost, your e.t.'s in a 3,300-pound car (yours may be lighter,) would probably be in the high 14's, if it hooks.
The first thing you could do, if you want to go faster than that, is install an alcohol/water injector and increase the boost level somewhat.
I have no idea what that might do for you, but I guarantee that you'd go faster/quicker. Just how much, I can't say...
Snowperformance has one for I like about $300.00 (Stage I.) I have one on my supercharged 360 Magnum and another on the turbo /6 car we're building.
Money well-spent, I think...
Chemical intercooling. A band aid that seems to work well.
I would email that seller and tell him what you want to do and ask him if that turbo is an appropriate size for your application. If he doesn't know that, he shouldn't be selling 'em...
Doing that might minimize your chance of a mistake that can cost you time and money.
It's worth doing, I think!
Good luck! :cheers:
